ABSTRACT:
A low-cost, portable copier for exposing a photosensitized sheet through a stencil placed thereon. The sheet and stencil, in the form of a "sandwich", are positioned on the copier's cover member which is then pivoted to a closed position against the copier's housing. A flash lamp article, including a tapered casing having a percussively-ignitable flash lamp therein, is inserted within the housing and activated by a resilient cantilever member located therein.
